Six Sigma Tools

Six Sigma methodology and projects tend to rely heavily on Six Sigma tools. Some project professionals, in fact, believe, that this method over-relies on Six Sigma tools. Critics claim that sometimes more attention is paid to reducing variation and searching for any significant factors and less attention is paid to developing robustness in the first place because Six Sigma project members focus too much on sticking to Six Sigma tools.

Six Sigma tools and projects emphasize the importance of testing and using Six Sigma tools, such as multiple regression techniques increases the risk of making commonly-unknown types of statistical errors or mistakes. A possible consequence of Six Sigma's array of P-value misconceptions is the false belief that the probability of a conclusion being in error can be calculated from the data in a single experiment without reference to external evidence or the plausibility of the underlying mechanism.

Six Sigma tools are mainly statistical tools. These are valid instruments for information analysis and process management, however, Six Sigma project members should avoid using them blindly. To summarize, Six Sigma tools include a few dozen of points:

  • 5 Whys
  • Poka Yoke
  • 5S
  • Process Mapping

When it comes to planning a Six Sigma project, project team members look into Six Sigma tools they are about to use, and plan their Six Sigma project accordingly. Six Sigma tools are frequently associated with project roles and Six Sigma belts, which outline which tools every team member should use depending on his/her belt level.
